Modelling the dynamics of krill populations in the Antarctic Peninsula region
age-structured population model and uses only the recruitment data to develop a model of the long-term ... dynamics. Data on the recruitment of the first and second age groups were used to derive different ... estimates of mortality rates. Both model approaches applied to the recruitment data for the first age class ... data. Using the recruitment data for the second age class produced higher mortality rate estimates ...
